² tn Or “dross.” The word refers to the scum or impurites floating on the top of melted metal.

¹ sn Traditionally “dross” (so KJV, ASV, NIV). The metaphor comes from metallurgy; “slag” is the substance left over after the metallic ore has been refined.

¹ sn The refiner’s fire was used to purify metal and refine it by melting it and allowing the dross, which floated to the top, to be scooped off.

¹ tn The traditional translation of “silver dross” (so KJV, ASV, NASB) never did make much sense because the parallel idea deals with hypocrisy—“fervent lips with an evil heart.” But silver dross would not be used over earthenware—instead it is discarded. Yet the MT clearly has “silver dross” (כֶּסֶף סִיגִים, kesef sigim). Ugaritic turned up a word spsg which means “glaze,” and this found a parallel in Hittite zapzaga[y]a. H. L. Ginsberg repointed the Hebrew text to k’sapsagim, “like glaze,” and this has been adopted by many commentators and recent English versions (e.g., NAB, NIV, NRSV, NLT). The final ם (mem) is then classified as enclitic. See, among others, K. L. Barker, “The Value of Ugaritic for Old Testament Studies,” BSac 133 (1976): 128-29.

¹ tn Heb “Is not my message like a fire?” The rhetorical question expects a positive answer that is made explicit in the translation. The words “that purges dross” are not in the text but are implicit to the metaphor. They are supplied in the translation for clarity.

² tn Heb “I will purify your dross as [with] flux.” “Flux” refers here to minerals added to the metals in a furnace to prevent oxides from forming. For this interpretation of II בֹּר (bor), see HALOT 153 s.v. II בֹּר and 750 s.v. סִיג.

⁵ tn Heb “like little.” This expression refers to what has little value: “little worth” (so KJV, NAB, NRSV; cf. BDB 590 s.v. מְעַט 2.d). The point of the metaphor is clarified by the parallelism: Silver is valuable; the heart of the wicked is worth little. Tg. Prov 10:20 says it was full of dross, a contrast with choice silver.

¹ tn The Hebrew כֶּלִי (keli) means “vessel; utensil” (cf. KJV, ASV, NASB). But purging dross from silver does not produce a “vessel” for the silversmith. Some versions therefore render it “material” (e.g., NIV, NRSV). The LXX says “that it will be entirely pure.” So D. W. Thomas reads כָּלִיל (kalil) and translates it “purified completely” (“Notes on Some Passages in the Book of Proverbs,” VT 15 [1965]: 271-79; cf. NAB). W. McKane simply rearranges the line to say that the smith can produce a work of art (Proverbs [OTL], 580; cf. TEV “a thing of beauty”). The easiest explanation is that “vessel” is a metonymy of effect, “vessel” put for the material that goes into making it (such metonymies occur fairly often in Psalms and Proverbs).
